In loom shuttles in which the spindles are pivoted so as to be movable up and down it is usual to employ plates between which the butt of the spindle extends and which-have their inner ends bent inward to form hooks to engage a head on the butter" the quill to prevent the latter when the spindle is depressed from slipping lengthwise on the spindle in the working of the shuttle in the loom. These hooks or claws becom broken oil or bent as the resultof careless handling in depressing the spindle with the quill thereon, necessitating disassembling of the shuttle parts to repair or replace them. The pressent invention aims to avoid this trouble by omitting the hooks or claws on the plates (which themselves may be retained as wearplates for the spindle butt) and providing on the spindle itself means to prevent the I quill from. slipping on the spindle in the way stated. This means comprises one or more spring hooks or claws and it is removable from the spindle so as to be replaced or repaired if a hook or claw becomes bent or broken, though the likelihood of any injury thereto is much less than in the case of the plates mentioned because the engagement therewith and disengagement of the quill therefrom can never take place in a way calculated to impose an undue strain on them. In the best form this means is a piece of spring sheet metal formed in the blank as an apertured disk with radial arms and in its ultimate form having said arms bent off lengthwise of the axis of the disk and pro Vided with inward camming abutments to engage the quill head. For removably securing the disk on the spindle the latter is provided with a shoulder near its butt and embodying the invention the disk being slipped over the spindle and 1929. serial no. 345,684:

An important feature of our invention, 1 regardless of the presence of means for holding the quill against slippage on the spindle, is that the latter is reinforced at the point where it is weakest, and where it frequently bends and sometimes breaks off as an incident of raising, or lowering it-to-wit, near the butt. This reinforcement is the result of rigidly securingon the spindle a thick .an-

nular member so'that the same abuts the shoulder at 14, such member in the present example being aflorded by the collar and disk and being preferably screwed on the spindle and jammed as the result of-the screwing action against said shoulder.

Having thus fully described our invention, what we claim is:"

In combination, with a shuttle spindle having an abutment near its butt,'a disk penetrated by the spindle and abutting the abutment and havinga spring arm extending toward the free end of the spindle and adapted to engage exteriorly of a package core ar ranged on the spindle and hold the same against slippage lengthwise thereof, and a collar secured on the spindle and holding the I disk against said abutment.-
